Question: A venturi is to be used for measuring the flow of air at 300 psia and 80F. The maximum flow rate is 1.0 lbm/s.

A venturi is to be used for measuring the flow of air at 300 psia and 80F. The maximum flow rate is 1.0

A venturi is to be used for measuring the flow of air at 300 psia and 80F. The maximum flow rate is 1.0 lbm/s. The minimum flow rate is 30 percent of this value. Determine the size of the venturi such that the throat Reynolds number is not less than 105. Calculate the differential pressure across the venturi for mass flows of 0.3, 0.5, 0.7, and 1.0 lbm/s. Assume = 0.5 for the venturi.
